No one doubts that Mbappe is a player who has excellent abilities in the front line, but the problem is that he does not work alone or in other words he must have a team that can work well together and provide good ball supply to the front line. Well now I have not seen Real Madrid able to distribute the ball that well. I even feel that Mbappe is unlucky because when he came Real Madrid had to leave one of their creative players in midfield. Real Madrid is currently having a lot of problems, so it is also a little disturbing to the team's overall performance. Like it or not it has to happen, because some of the changes made also have an impact on the game. Not meaning to say they played badly, but they have not been at their best in showing their best game.
Mbappe has just joined the Real Madrid team and he has not found a strong chemistry with his teammates so I think Mbappe needs time to adapt and there is nothing wrong with that.
And for Real Madrid's performance which is currently struggling because many of their main players are injured so that it has a big impact on the performance of the Real Madrid team which is declining and inconsistent.
In terms of individual quality, Mbappe is quite good, no one doubts it and he needs time to be able to contribute greatly to the Real Madrid team, I'm sure that will happen.
